July 7 7100 ft, ½ mi. S Donner Pass, Placer Co., Calif - 1
scolded (?) us from edge of chaparral
(huckleberry oak, manzanita, Eleanthus) and
conifer forest SE of Mary Lake.
July 9 at least 1 heard giving the “quark” song
in this same area; but such songs have
the
in general region, pretty much ceased.
July 11 6500-6300 ft, 3+ mi. S L Van Norden, Placer Co., Calif.
2 “singing” birds heard in forest - chaparral
areas on an early a.m. visit.
July 13 7100 ft, ½ mi. S Donner Pass - call notes of
mild alarm, the only ones heard here today
[with absence of singing ??] I did not encounter
the species again until :
Aug 8 S side Donner L, 6000 ft., Nevada Co., Calif - 1 adult
accompanied by 3+ downy YOUNG which
had considerable wing feather showing.
They ran slowly along road s into moist
shrub-herb understory of opening in fairly
dense forest of fir (red or white ?), Jeffrey Lodgepole;
Aug. 10 7100 ft, ½ mi. S L Van Norden, Placer Co., Calif - an adult
and 7+ YOUNG flushed from a lone outlier
fir tree by forest edge, across a nearly bare
slope s into cherry & willow thickets at
the base of the gravelly S-facing open ridge.
The young were only about ½ size but flew well.
Aug. 25 7100 ft, ½ mi. S Donner Pass [see above] - about 10 flushed
or ran into chaparral of same area as July records;
several of them were well-grown immatures.
